Sending a high resolution file to a bitmap

I often need to take screen shots of my work and paste that into Word or email documents.   I can take a screen capture, but the resolution is often quite poor.  I then do a print preview, and the appearance changes quite dramatically and the resolution although better is not great.  When I try to save as a *.jpg, the system just goes into an infinite loop. 

There was an interesting sounding macro available here

which I tried, but it was only suitable for 32bit operating systems. 

I would appreciate any help, like perhaps an updated 64 bit version?
